cuba-memorys vs synaptic-memory

cuba-memorys: Cuba-Memorys is a Model Context Protocol (MCP) server that gives AI coding assistants long-term persistent memory. It uses a knowledge graph, neuroscience-inspired algorithms like FSRS-6 adaptive decay, Hebbian learning, and dual-strength memory, along with anti-hallucination grounding. The latest version 2.0.0 is a complete Rust rewrite with 12 tools and sub-millisecond performance.; synaptic-memory: Synaptic Memory is a knowledge graph and MCP tool server for LLM agents. It automatically ingests data from various formats into a structured graph, then provides 29 atomic tools for agents to explore. No LLM cost at indexing time.
